Test excepting nontyphoidal Salmonella Campylobacter coli 66•53% 90•48% increase respectively. This adult patients.The activity changed profoundly alongside NPIs Greater reductions test found almost patients, further large differences by age geography. Lifting will lead resurgence infections, particularly children whose immunity may not been developed and/or waned.China Mega-Project on Infectious Disease Prevention; National Natural Science Funds.
